SLEEP GROOVE isn’t just another sleep book. Written by Olivia Walch, Arcascope’s CEO, it offers readers an accessible and entertaining tour of the complexities of circadian rhythms and sleep. The book breaks down advanced concepts with easy-to-understand explanations, using humorous analogies, eye-catching illustrations, and comics to guide readers through the often misunderstood machinery of their […]
Let’s say I want to boost circadian amplitude as much as I can. What light/dark schedule should I put myself on? This is a very tough question to answer experimentally, given how many possible light/dark schedules there are (infinite) and how expensive experiments like this can be (near infinite). But mathematical modeling can give us […]
“If you want to become an earlier chronotype, get more zeitgeber during your phase advance region and less zeitgeber during your phase delay region.” My head is in my hands. At parties, if no one stops me, I will often rant about math’s UI/UX problem. Listen, I say. We just casually drop that sin-1(x) is […]
This blog is the spiritual sequel to our last blog post on ways of measuring sleep regularity. Unlike the last one, though, which was based on an excellent review article, this post is Olivia’s off-the-cuff (and extremely wonkish) thoughts on the topic of circadian amplitude. There’s a reason for a lack of formality, though, which […]
Recall, if you will, that elementary school classic, “Guess How Many Beans Are In The Jar.” Over the years, I’ve guessed at many beans in many jars, but none sticks with me like the first: Halloween, 1998. I was dressed as the Mona Lisa. The jar was filled with jelly beans. I counted all the […]
Like anyone talking about anything, I tune my content to the audience. When I talk about our tech to travelers, I tell them our apps can help them get over jet lag faster. When I talk about our tech to shift workers, I highlight how we can help them sleep more and get them to […]
My family spent the last week of the year visiting my wife’s family in the Seattle area, filled with the warmth of family. Even though we were also filled with lots of great food, it didn’t lead to lots of satisfaction with said food. Maybe I would feel full (or overfull) temporarily, but soon enough […]
In the realm of medical research, the study of circadian rhythms has gained increasing attention in recent years. Dr. Marc Ruben, a postdoctoral researcher at Cincinnati Children’s Hospital, is at the forefront of this exciting field. In a candid and insightful interview, Dr. Ruben discusses his work, insights, and the potential impact of circadian medicine […]
Cold and flu season are starting in the southern hemisphere, while allergy season is in full swing in the global north. Both of these are linked to our immune systems, which are built out of many different organs, hormones, and free-roaming, invader-killing cells such as T-cells. Because infection can happen anywhere, our immune systems interact […]
I was reading this article on circadian variation in immune response a couple of weeks ago when I came across this quote, seemingly engineered in a lab to get my adrenaline pumping: “McKeating [says] that when she thinks back to the long line of failed vaccines in this field, she wonders whether timing may have […]
